The hose fitting may be leaking. Mine are and all 4 hoses are getting replaced in the offseason.
I also got the cylinder rebuild kit from 5 star. It replaces all of the gaskets inside the cylinder. You would see fluid coming from the piston if you had a bad internal seal. Mine were pissing...
I’m dealing with this exact issue right now. There’s been a ton of troubleshooting but I still have to check to see if the risers or manifold are clogged and do a pressure test on intake plumbing to look for cracks.
